These Canada Geese are flying over the house in standard V-formation. According to The Sibley Guide to Bird Life and Behavior, birds fly in V-formation to gain extra lift from their neighboring birds. This makes staying aloft easier and probably helps a lot over long migrations.
Of course, even with the help in flight they still need to rest. These geese are swimming on the Willamette River.
Canada Geese are everywhere around here, as they are in many places in the U.S. I’m not sure how many stick around and how many just pass through. But I’d guess that quite a few choose to live here considering our climate, abundance of water, and the fact that they seem to always be here. According to OregonLive, many of the geese in our area start to head north around April to breed up in Alaska, Canada, or Russia.
